Exactly five years ago today, Apple officially released its entry into the mobile phone market, the iPhone. Immediately loved by customers the world over, ridiculed by the competition, and, in my book, not particularly innovative feature-wise, it changed the mobile phone industry virtually overnight. Love the iPhone or hate the iPhone, its industry-changing impact is evident.

Android is not a phone, it is an OS. By your own metric, the iPhone is generally and in most geographies the "best" smartphone. At best, in most geographies, there is only 1 phone that remotely approaches the iPhone (the latest and greatest Samsung Galaxy) and it will generally only outsell the iPhone for a few months of its initial availability.

Here's a handy guide for you : Android as an OS is more successful than iOS, but iPhones as individual handsets are more successful than every individual Android handset. People like to think that they use a successful platform, so Android users like to discuss OS market share, iOS users like to discuss handset sales, and WP users like to discuss the amount of desktop Windows devs that are somehow all going to migrate to their platform in a month. The relevance of these various numerical indicators, or even the extent to which they can be compared when discussing different platforms, is irrelevant to this kind of debate, which is pretty much the grown-up variant of a dick measurement contest.
